You are doing nothing wrong, wind is the great equalizer when it comes to aircraft, even my 40+% planes get blown with the wind. But on the little profiles you do not have any weight and have to play with it a lot more to get it to hold in one place and it sounds like you have the principal down, it just takes practice with the wind and finding the perfect angle to get it to hold its own. Also remember a light wind to you is a hurricane to a 8lb profile, they need more finesse, practice keeping it in a normal torque roll and letting the wind blow it down the runway. after that practice letting the wind blow you backward down it and flying it back to you, that will help you find the angle to hold it in one place.
